Rajesh Radhakrishnan created CASSANDRA-12700:
------------------------------------------------
Summary: During writing data into Cassandra 3.7.0 using Python driver 3.7 sometimes Connection get lost, because of Server NullPointerException
Key: CASSANDRA-12700
URL: https://issues.apache.org/jira/browse/CASSANDRA-12700
Project: Cassandra
Issue Type: Bug
Components: Core
Environment: Cassandra cluster with two nodes running C* version 3.7.0 and Python Driver 3.7 using Python 2.7.11.
OS: Red Hat Enterprise Linux 6.x x64,
RAM :8GB
DISK :210GB
Cores: 2
Java 1.8.0_73 JRE
Reporter: Rajesh Radhakrishnan
Fix For: 3.7
In our C* cluster we are using the latest Cassandra 3.7.0 (datastax-ddc.3.70) with Python driver 3.7. We are trying to insert 2 million row or more data into the database, but sometimes we are getting "Null pointer Exception". I am quoting the Exception here.
Any help would be highly appreciated.
We are using Python 2.7.11 and Java 1.8.0_73 in the Cassandra nodes and in the client its Python 2.7.12.
